Type material. Holotype: ♂ from Hacienda Hierba Buena , Sierra Nevada de Santa Marta , San Pedro de la Sierra, Ciénaga, Magdalena, 2104 m, 10.895138°N, 73.99961°W, 3.III.2017, L. Martínez (ICN-Ar 9974) . Paratypes: 3♀ 1♂, the same data as holotype (ICN-Ar 9975–9976) ; 1♂ from same locality, El Chuscal, 2300 m, 10.8°N, 73.65°W, 16.VI-1.VII.2001, J. Cantillo (IAvH-I-3116) .

Etymology. The epithet honors an extinct indigenous civilization from the Sierra Nevada de Santa Marta, Caribbean region of Colombia, which inhabited the Cesar, Magdalena and La Guajira departments, and whose descendants currently correspond to the Arhuaco, Kankuamo, Kogui and Wiwa peoples. To be treated as an arbitrary combination of letters, and hence without the need to agree in gender with the genus.

Diagnosis. Males of this species are distinguished from those of the remaining species in the genus by their long embolus (e) which emerges prolaterally and has the final portion inserted in the concavity of the accessory tegular apophysis (Ta), and a short and rectangular retrolateral tibial apophysis (RTA) ( Figs 14–17 ). Females differ from the others by the anteriorly placed spermathecae (sp), lateral copulatory ducts (cd), the posteromedial copulatory openings (co) and the overhanging projection arising between the copulatory openings reaching the posterior margin of the epigynal plate; the projection has an intermediate length between L. guamani and L. lorax ( Figs 18–19 ).
